I think there are so many other tokens than XRP that should be considered, I'm not badmouthing XRP but the performance in the field will show the results.
and I think xrp will be replaced.
I also think there are many other projects better to invest in than xrp. But I'm not sure about it being replaced, at least not in the near future. If xrp was able to counter with sec, it means they have strong backers. That's the only reason why the coin is at the top.
